Polyurethane grouting material is a chemical slurry composed of polyurethane prepolymer and additives (solvent, catalyst, retarder, surfactant, plasticizer, etc.)
Classification specification
Can be divided into water-soluble (hydrophilic) and oil-soluble hydrophobic) 2 categories
Features
Waterborne polyurethane grouting material
▲ It can react with water in the presence of a large amount of water. After solidification, it forms an impervious consolidated layer, which can block the water inrush.
▲The carbon dioxide gas is generated at the same time of the curing reaction. The initial gas pressure in the closed grouting system further presses the low-viscosity slurry into the deep cracks and the pores of the loose formation, so that the porous structure or the formation is densely packed, and the late bubble encapsulation In the colloid, a bulky elastic cured product is formed.
▲It will not be drained by water; the formed elastic consolidation body can fully adapt to the
deformation of cracks and foundations.
▲The viscosity of the slurry is adjustable, and it can fill the slit of about 1mm; the curing speed is convenient to adjust.
▲It can be used not only for plugging but also for reinforcement and reinforcement. It can also be used as a coating agent with good anti-seepage and anti-corrosion properties.
▲ After solidification, a solid elastomer is formed. The volume of the elastomer can be expanded several times. The nco content of the cyanide is high, so the elasticity of the solid is poor.
Scope of application
▲ Oil-soluble polyurethane grouting material has high consolidation strength and good impermeability. It is used for reinforcement of foundation and waterproof plugging.
▲Water-soluble polyurethane grouting material has good hydrophilicity and large water content. It is suitable for grouting and plugging of wet cracks, plugging water in moving water stratum, and protection of wet soil surface layer.
